A simulation model for AGC studies of hydro-hydro systems

AGC studies pertaining to hydro-hydro systems have received little attention. In this paper a simulation model for AGC studies of such systems has been proposed. The difficulty in extending the traditional approach [Elgerd OI. Electric energy systems theory. New York: Mc-Graw Hill; 1983.] for such systems is overcome by assuming that all areas in a system operate at the same frequency. The proposed simulation model is obtained by ignoring the difference in frequency between control areas, unlike the traditional approach, where in each area is assumed to operate at a different frequency. The features of the proposed model have been demonstrated through simulation studies.
